The objective of this study was to evaluate the useful life of lemon biscuit under different preservation systems. Lemon biscuit is a local food produced in the department of Cordoba, Colombia, it is very popular for its particular flavor and low cost. The samples were obtained from 3 local producers in the Lower Sinu region, to which potassium sorbate (0.1%) was added as a preservative during their processing. The samples were packed in two types of package (low density, polyethylene and polypropylene) and stored at temperatures of 28 and 32°C for 24 days, a lemon biscuit without sorbate and without any type of packaging was used as the control sample, which is the way it is locally marketed. Microbiological (aerobic mesophiles, lactic acid bacteria, molds and yeasts, total and faecal coliforms, Bacillus cereus and S. aureus), physicochemical (pH, acidity and weight loss) and sensorial parameters (color, taste, appearance and texture) were evaluated during storage at day 0, 6, 12, 18 and 24, respectively. Microbiological parameters of mesophiles, molds and yeasts presented significant differences (p<0.05) between treatments. Treatments have highly significant differences (p<0.001) regarding the attributes of color, appearance, taste and texture of the food. In conclusion, the flavor attribute was the determinant variable when estimating the durability of the analyzed product, the added with 0.1% potassium sorbate and packed in polypropylene bags reached 12 days of shelf life.

This study evaluated the effect of acid concentration and reaction time in the lintnerization process on the physicochemical, structural and rheological properties of native yam starch (Dioscorea alata cv. Diamante 22). The lintnerization process involves chemical modification with hydrochloric acid to produce starch for the food, paper and textile industries. The acid hydrolysis of yam starch produced low dextrose equivalents (D.E 4.7%) and yields between 83 and 96%, as well. Slight changes to the granule surface, which mainly affected the amorphous part of the granule and reflected in the increased crystallinity, reducing the Water Absorption Capacity (WAC) and swelling (SP). For to the native starch, otherwise, when moderate acid hydrolysis is applied. A yield between 83 and 96%, slight changes on the granular surface (exo-corosión superficial). A reduction was observed in the initial gelatinization temperature from 82.1 to 77.6°C and maximum viscosity (1790 to 1656 MPa.s) when subjected to severe lintnerization treatments. The lintnerization process improved the stability of the starches during heating and decreased their tendency to retrograde, resulting a gel of stable consistency, suitable for the processed food industry.

This study aimed to optimize the enzymatic hydrolysis of rainbow trout (Oncorhynchus mykiss) viscera with the enzyme alcalase® 2.4 L to found the highest the Degree of Hydrolysis (DH). In vitro evaluation of the optimum conditions (pH and temperature) was performed to maximize the Proteolytic Activity (PA) of alcalase® 2.4 L with the rainbow trout viscera. The optimal conditions for maximum enzymatic activity were a pH of 8.5 and a temperature of 60°C. Response Surface Methodology (RSM) was used to evaluate the effect of the enzyme/substrate ratio (10-30%), substrate concentration (2.0-6.0%) and temperature (45-65°C) on DH. A substrate concentration of 5.53% and an enzyme/substrate level of 30% were found to be the optimum conditions to obtain the highest DH (27.6%). The Michaelis-Menten plot indicated that these conditions were not in the saturation area.

The main goal of this study was to develop an innovative product based on food from vegetal origin (beet and oat) incorporated in a dairy product (koumiss). Raw materials were pasteurized milk, bacterial inoculum, beet and oat. Beet and oat were incorporated according to three formulations. The sensorial analysis (5 points hedonic scale) was done by a panel constituted by 30 non-trained personnel who considered the following attributes: aroma, taste, color, texture. The nutritional analysis was estimated considering the information in the Colombian table of food composition (2015 version). As a result, koumiss presented viscous texture similar to commercial koumiss. Additionally, the content of micronutrients was identified (from major to minor): riboflavin (1.7 mg), iron and zinc (both 1.2 mg), niacin (0.9 mg), thiamin (0.2 mg), vitamin A (97.5 UI) and folic acid (41.7 &mug) based on 200 mL. Thus, there was an innovation in the presentation of this food product, which allowed improving their nutritional value. Finally, the developed product achieved a sensorial score of 4, which indicated its acceptation by consumers and commercial potential.

The optimization of the process parameters was the aim of this study to obtain a powder from the pumpkin juice (Cucúrbita moschata) using the spray drying method. For the optimization of spray drying a surface response methodology was used, considering a central design composed of three factors: Maltodextrin concentration (10-25%), the temperature of the air inlet (150-170°C) and feed flow rate (4000-5000 mL/h) and the response variables evaluated to determine the optimal conditions of the process were: powder yield, humidity, hygroscopicity and solubility of the powder. The results of the statistical analysis indicate that all factors significantly affected the response variables, an increase in the addition of maltodextrin concentration to the pumpkin juice flow, generates an increase in yield, solubility and lower hygroscopicity values, the increase of the inlet temperature and the feed flow rate produced a decrease in the moisture content of the obtained powder. The optimal conditions of the process were reached with a 25% of maltodextrin concentration, 170°C for the air inlet and a flow rate of 4000 mL/h. These process parameters, allow obtaining a powder with a yield of 62.70%, humidity 3.40%, hygroscopicity 28.70% and solubility 71.5%, indicating a technological opportunity to generate and economic value to the pumpkin fruit, which allows improving the life quality of the country's farmers.
对喷雾干燥法从南瓜汁(Cucúrbita moschata)中提取粉末的工艺参数进行了优化。为了优化喷雾干燥工艺,采用表面响应法,考虑由三个因素组成的中心设计:麦芽糊精浓度(10-25%)、进风口温度(150-170℃)和进料流量(4000-5000 mL/h),并评估响应变量以确定最佳工艺条件:产粉率、湿度、吸湿性和粉末溶解度。统计分析结果表明,各因素对响应变量的影响均显著,在南瓜汁流量中加入麦芽糊精浓度的增加,会产生产率、溶解度和吸湿性值的增加,进料温度和进料流量的增加会产生所得粉末含水量的降低。最佳工艺条件为麦芽糖糊精浓度为25%,进气温度为170℃,流速为4000 mL/h。通过这些工艺参数,可以得到得率为62.70%、湿度为3.40%、吸湿率为28.70%、溶解度为71.5%的粉末,表明南瓜果实具有技术生产机会和经济价值,可以提高我国农民的生活质量。

Formed by 84 families, considered a settlement of victims of the armed conflict of the departments (Magdalena, Cesar, Bolívar), established approximately in the year 2000. The type of study was descriptive with a quantitative approach. The 69 households surveyed showed a prevalence of food insecurity of 92.7%, with both scales (higher-than the national proportion reported in ENSIN 2010, 42.7%). However, in the Latin American scale of food security, for having a stricter filter, the level of severe food insecurity was 59.4%, higher than the one showed by the food security scale at home with 23.2%. The food insecurity was significantly associated with sociodemographic characteristics, housing conditions and nutritional status. These results indicate that the settlement must have access to the food and nutritional security policies designed by the government for post-conflict actions.
该研究的目的是通过应用2010年全国营养状况调查中使用的粮食安全量表,确定Villa Clarín家庭中粮食和营养安全的普遍程度。Clarin别墅位于200米的Clarin海峡,毗邻马格达莱纳河,位于马格达莱纳省Sitio Nuevo市巴勒莫村的前面。由84个家庭组成,被认为是武装冲突受害者的解决办法(马格达莱纳,塞萨尔,Bolívar),大约于2000年成立。研究的类型是描述性的定量方法。接受调查的69个家庭的粮食不安全发生率为92.7%,这两项指标均高于2010年ENSIN报告的全国比例(42.7%)。然而,在拉丁美洲粮食安全规模中,对于具有更严格的过滤,严重粮食不安全水平为59.4%,高于国内粮食安全规模所显示的23.2%。粮食不安全与社会人口特征、住房条件和营养状况显著相关。这些结果表明,定居点必须能够获得政府为冲突后行动制定的粮食和营养安全政策。
